Disclosed are a water area surveillance robot for collecting water area information and a control method thereof. The water area surveillance robot for collecting the water area information comprises a ship body, and a drive unit, a main control unit, a water area information collection unit, an energy supply unit and a wireless communication unit, which are installed on the ship body, wherein the ship body is of a cylindrical ship body structure, the drive unit is composed of two ducted propellers which penetrate through the ship body, the two ducted propellers are symmetrically installed on two sides of the ship body, each ducted propeller is a duct with an internal propeller, each duct is made of light and solid material, a filter screen is installed on a port of each duct, and each ducted propeller is located in the middle of the interior of each duct. The control method of the water area surveillance robot for collecting the water area information includes that the water area surveillance robot for collecting the water area information is pushed forwards by relying on water currents, and when the water area surveillance robot for collecting the water area information enters a dead water area, drive motors of the ducted propellers are started, the ship body is controlled under guidance of an electronic compass module and drainage basin information, and then the ship body achieves posture adjustment and breaks away from the dead water area.
